TIN VESSEL.

SPECIFICATION forming part of Letters Patent No. 225,204, dated March 9, 18180. Application led November 28, 1879.

To all 'whom it may concern Be it known that I, AOSCAR J. BAGKUS, of the city and county of San Francisco, and State of California, have invented certain new and useful Improvements in Tin Vessels; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings. y Figure lis a perspective View of a can constructed in accordance with my invention. Fig. 2 is a detail view of a section of a rim.

Tin cans and vessels always wear out first at the corners and anglesfirst, because these parts are most subjected to wear; and, secondly, because they are more difficult to keep clean and dry. On this account a heavy and superior quality of tin is used when a durable tin vessel is to be made.

My invention relates to an improvement in the construction of tin cans and vessels by which I am able to use an inferior quality of tin to form the body of thecan or vessel, and at the same time render it strong and durable.

It consists 4in the employment of a rim which is made of a heavy and superior quality of tin, and which is united to the body of in'- ferior tin, so as to give it durability and stiffness, as hereinafter described.

In constructing a tin vessel, I make the body A in one piece and its upper rim, b, in I use an inferior quality of tin to make the body A, and I leave its edges single and plain. The rim or edge piece b, I make of a better quality of tin, using a narrow strip, as shown.

One edge of this strip I then coil or turn over, so as to form a rounded or beaded surface for the edge ofthe vessel, while the other edge is left plain. This edge piece or rim I then bend to the required size to fit around the edge of the body A and solder its ends together, with its bead resting upon or against the edge of the vessel. The plain edge of the strip or edge piece I then slip on inside of the edge of the body A and solder it in place, so that its beaded edge will form the edge or rim of the body.

If desired, the edge of-the strip can be bent around a wire, so as to form a stiff and rigid edge. Y

By this means I am able to make tin vessels much cheaper than when a singlel quality of tin is used, and at the same timeV the vessel will be equally as serviceable.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

vAs a new article of manufacture, a tin vessel having its edge provided with a separate strip of sheet metal, with the under part of its bent beaded portion resting against the body of the vessel and its plain portion fitting snugly against the inside of and around the mouth of the vessel, substantially as and for the purpose set forth.

In Witness whereof I have hereunto set my hand and seal.

OSCAR J. BACKUS.
